Abstract

The present invention provides a process for producing low-emission flexible polyurethane foams having a reduced odor and reduced fogging by reacting a) polyisocyanates with b) compounds having at least two hydrogen atoms which are reactive toward isocyanate groups, c) blowing agents wherein polyether alcohols which have been prepared by addition of alkylene oxides onto compounds derived from renewable raw materials using DMC catalysts are used as compounds b) having at least two hydrogen atoms which are reactive toward isocyanate groups.
